Ash gourd is an under-exploited but important vegetable crop in which genetic diversity has been studied to a very limited extent. Field experiments were, therefore, conducted during the rainy seasons of 2015 and 2016, in order to study the genetic diversity in 18 ash gourd genotypes (11 landraces + 7 released varieties). The genotypes were grouped into three clusters. Clusters I, II and III contained six, three and nine genotypes respectively. Cluster III consisted of all the released varieties except Pusa Ujwal. | Genetic diversity analysis of ash gourd Benincasa hispida Thunb. Cogn. germplasm by principal components
